SIDE-LEAK OR SAND-WALL WASHER FOR OIL-WELLS..

SPECIFICATION forming part of Letters Patent No. 277,607, dated May 15, 1883. Application tiled January 1883. (No model.)

To all whom 'it may concern:

Beit known that I, JOHN M. REARDON, a citizen of the United States ot America, residing at Shippensville, in the county of Clarion and State ot' Pennsylvania, have invented certain new and useful Improvements in Side- Leaks or Sand-Wall Washers forOil-Wells; and I do hereby declare the following` to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to means t'or washing the oil-producing rockin oil-wells and preventing the collection of pnrat'line on the walls of the well. l

The object of my invention is to'provide a leak or sand-wall washer for the purpose mentioned which can be drawn out of the well by the sucker-rod Without pulling the tubing up or doing any injury to it.

In the ordinary means ot' a sand-leak in the wall ofthe tubing for washing the rock, if the apparatus becomes clogged by sediment or detritus, it is sometimes necessary to pull up the tubing to remove the difficulty; and to overcome this expensive and hazardous labor my invention is more specially designed.

Myinvention consists in a leak-valve adapted to tit within the bore of the tubular seat, provided with suitable packing, and formed so as to be separable and ehambered to receive a strainer, as hereinafter set forth.

My invention further consists in a tubular seat provided with screwthreaded ends to receive and couple the ends ot' the tubing, and

formed with one or more ports intermediately arranged, in combination with a leak-valve adapted to tit within the bore of the tubular seat, provided with suitable packing, and formed so as to be separable and chambered to receive a strainer.

My invention further consists in a tubular seat provided with screw-threaded ends to receive and couple the tubing, and formed with `one or more intermediate side ports, a leakvalve adapted to fit within the bore of the tun bular seat, provided with suitable packing, in combination with a strainer.

My invention further consists in the novel combination and arrangement of parts, as will be more fully hereinafter described, and specilically claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a side view ofthe seat with the leak-valve and sucker-rod inserted. Fig. 2 is a sectional view ofthe same, and showing the strainer with internal construction. Fig. 3 is a side view ot' the seat. Fig. 4 is a view ofthe leak-valve, the part being separated'to receive the strainer. Figzf a view of the strainer. Fig. 6 is a View ofthe seat with the Well-tubing connected thereto.

A is the seat, (see Figs. l and 3,) which is tubularinconstruction,andreamedouts'lightly tapering, with the small end ot' the bore in the direction ot' the bottom ofthe well, the object of which is to afford a seat for the lealvalve, so as to prevent it from passing through beyond a given point. In the sides of the seat are formed one or more ports, n, arranged intermediately between the ends ofthe seat, and in the ends ofthe seat are screw-threads to re ceive the screws cut on the tubing' and secure the same in the seat.

B is the leak-valve, formed in two parts,with open caged ends, and are connected andsecured valve is shaped exteriorly to accurately tit the taper of the bore otl the seat, and is preferably provided or formed with a soft-metal packing covering the part b, in order to insure a tight connection between it and the bore ofthe seat. In the bodyot' this leak-val\'e, at a point therein which will come below the top ot' the ports in the seat, is formed the side-leak c, which is a screw-plug let in the leak-val ve and perforated to admit of the ilow through it. In both ends ot' the leakvalve, distance, are cut screw-threads c, and the body between the terminus ot' these is reamed out to a larger diameter than the diameter of the bore throughV the screw-threaded portions. This construction enlarges the space between the surface of the strainer and theI wall ofthe leak-valve, and admits the body ot" the strainer to pass through the bore of the valve land engage with the screw-threads in the lower end.

(l is the strainer, made ot' metal pipe, and provided with screw-threads on one end, and another screwthread portion at near the other end so arranged as that they respectively en bythe one screwing into the other. This leak# in the inside for a proper IOO gage with the screw-threads out in the bore of the leak-valve. The body intermediate between the screw-threaded portions is turned down of asmaller diameter, and this part is perforated with a series of small holes, the purposes of which are well understood. For con- .venience in placing and removing the strainer the upper end is recessed at d, to ai'ord means for inserting a bit or lever.

D is the rod passed through the. leak-valve and strainer and connecting with the suckerrod. This section of the rod is provided with ordinary screw-couplings, e, made larger than the bore ofthe cages, in order that when drawn up against the lower cage a seat will be afforded for the device, and by which means the leakvalve with the strainer can be drawn up out of the tubing. f

The adjustment, uses, and operation of my device are obvious to those acquainted with the art. ln adjusting the device in the well within the working-barrel, or at any other point where necessary, sections of the tubing are secured in the seat, and the leak-valve with the strainer adjusted therein is passed over a section of the rod and let down until it finds its rest in tbe seat. The operation is that when the oil is pumped up it must pass through the strainer, as nothing can pass through the perforations of the strainer which would not readily pass through those of the leak-valve.

In case the leak or the strainer becomes clogged, the device is readily withdrawn and cleaned, and again returned for uses intended.

`If two or more of these devices are used in the samewell, it is seen that the lower one must be smaller in order that it may pass through the bore ofthe upper one.

What I claim-as my invention, and desire to secure by Letters Patent, is

1. A leak-valve provided with a side-leak,

and adapted to t within the bore of a tubular tapered seat, and formed in two parts, tbeinside being chambered and provided with screwthreads to receive and retain. a strainer, substantially as described.

2. A leak-valve provided with a side-leak, andadapted t-o fit within tbebore ofa tubular tapered seat provided with a suitable packing, and formed in two parts, the inside being chambered and provided with screw-threads to receive and retain a strainer, substantially as described.

3. A tubular seat formed with one or more side ports and provided with screw-threaded ends, in combination with a leak-valve provided with a side-leak and adapted to t within the tubular tapered seat, and formed of two parts, the inside being chambered and provided with screw-threads to receive and retain a strainer, substantially as described.

4. A tubular seat formed with one or more side ports and provided with screw-threaded ends, in combination with a leak-valve provided with a side-leak, and suitable packing adapted to fitwithin the tubular tapered seat, and formed ot two parts, the inside being chambered and provided with screw-threads to receive and retain a strainer, substantially as described.

5. In combination with a tubular seat formed" with one or more side ports andscrew-threadedj ends, and a leak-valve formed with a side-leak and adapted to fit within the tapered tubular seat, a strainer provided with screw-threaded ends and body of smaller diameter, substantially as described.

6. In combination witha leak-valve, a sideleak formed of a perforated plug, substantially as described.

7. ln combination with the tubing of an oil` well, a tubular seat formedwith side ports, a leak-valve provided with a side-leak and adapted to tit within the tapered bore of the tubular seat, and a strainer, substantially as described.

In testimony whereof I aix my signature inv presence of two witnesses.
